^ the DE model isn't extremely accurate tho (great for SD in 2001.)
Notice the extreme hump on the TB superstructure and the horizontal top and up-sloped bottom of the "photon exhaust" in the image in this post
(compare to seam above as well as deck lines you overlayed.)
Now compare that to this image from TWOK
Notice that the "photon exhaust" top is not parallel to the seam (declination in the cut going forward) but the bottom is. Some thing that bears up when examining the studio model (large image)
So IMO not a great standard and not one to be used to make accurate statements about the refit Enterprise.
